Answer:

Step-by-step explanation:
If x is directly proportional to y, then


where, k is constant of proportionality.
We know that,
1 miles = 1.60934 km
It is given that x-miles and y- kilometers. Constant of proportionality is 1.60934.

Hence, the required equation is
.
Answer:
0
Step-by-step explanation:
The product of first 100 whole numbers will be 0. It is because 0 is also a whole number and any thing multiplied by 0 will give out answer to be 0,no matter how long the series is
The weight (y) will always be positive, the number of balls (x) too. So without the bucket, the function would be:
y = 1.6x
Now we have to add the weight of the bucket which is 2lb, or the same 32oz.
So the function results:
y = 1.6x + 32 (oz.)
If there is 1 ball, the weight is 1.6+32 = 33.6 oz. If there are no balls, the weight is 0 + 32 = 32 oz.
It is very important that all terms in the equation are in the same units, oz. in this case. Otherwise, if you do not translate lb. to oz. the resulting equation will be wrong.
If you need the equation expressed in lb., you only need to multiply the equation by 1lb/16oz:
y = = 0.1x + 2 (lb.)
Since the common denominator is the same, ignore the 2 and do -4/5-2/5= -6/5
-6/5 as a mixed number is -1 1/5. Add the 2 to the 1 and you get: -3 1/5
Another method:
Make everything an improper fraction:
-14/5-2/5 = -16/5= -3 1/5
